"After the award of the Viaduct 5 and Viaduct 6 packages in January (to IJM Construction Sdn Bhd and Ahmad Zaki Sdn Bhd respectively), and the award of the underground package in March (to MMC-Gamuda JV), these awards show further progress for the Sungai Buloh-Kajang line," said Datuk Azhar Abdul Hamid, MRT Corp CEO, in a statement on Wednesday.

The packages - Viaduct 1, Viaduct 4, Viaduct 7 and Depot 1 - are worth RM3.22 billion and include the construction and completion of viaduct guideways and related works while the depot package is for the construction of the Sungai Buloh Depot and related buildings.

Sunway Construction was awarded package V4 worth RM1.17 billion for works between Section 17, Petaling Jaya and the Semantan Portal, while Trans Resources Corporation was awarded the Depot package worth RM458.98 million for works related to the Sungai Buloh depot in an open tender category.

Meanwhile, package V1 worth RM1.09 billion, a bumiputera exclusive package, covering works between Sungai Buloh and Kota Damansara was clinched by Syarikat Muhibbah Perniagaan and Pembinaan Sdn Bhd and package V7 worth RM499.98 million was secured by MTD Construction Sdn Bhd for works between Bandar Tun Hussein Onn and Taman Mesra in Cheras, said MRT Corp.

"The evaluation looks at various factors, including technical capability, financial strength and of course price. The key is finding a fit that will ensure the project gets the best technical input from a capable contractor while maintaining costs within our expectation for the packages," he explained.
